Abstract
Indonesia is among the earthquake prone countries with the largest deaths percentage caused by building collapse. On the skeletal system of earthquake resistant structure, based on Seismic Provisions for Structural Steel Buildings (AISC) 2010, a performance evaluation of energy dissipation to link beam (e) in the Eccentrically Braced Frames (EBF) type K-braces system has been done, since the link beam acts as a damper withstand shear and bending forces due to earthquake loads. Evaluation was done on short link beam (e ≤ 1,6Mp/Vp) vertical web stiffener of 20 story EBF structure located in Padang -Sumatera Barat, by studying the performance of short link vertical web stiffener blocks due to cyclic loading in the form of displacement at a certain amplitude of the initial yield velocity (Δy) varying by 1Δy, 2Δy, 5Δy, and 10Δy considered to represent extreme seismic loads. The building was designed according to ANSI/AISC 2010 using software Extended Three Dimensional Analysis of Building Systems (ETABS) version 2016, with an earthquake load in accordance with SNI 1726:2012 which refers to ASCE/SEI 7-10. The results showed that dissipation energy of short beam link vertical web stiffener with loading below maximum load limit, on increasing loading (1Δy, 2Δy, dan 5Δy), the greater the cyclic load increase the percentage of energy decrease increase, and the number of plastic cycles before the impedance decreases, while the constant loading (10Δy) has a relatively same decrease in energy per cycle and increased number of plastic cycles before the collapse.
